Collaborators

Willem Stassen, University of Cape Town 
 
Willem Stassen (BTEMC, MPhil EM, PGDip Appl. Ethics, PhD) is a South African emergency care practitioner and Associate Professor of Emergency Medicine at the University of Cape Town. He also serves as the Deputy Director of the WHO Collaborating Centre on Integrated Clinical Care. With clinical experience in critical care retrieval across ground, helicopter, and fixed-wing transport, Stassen’s research focuses on optimising prehospital emergency care systems, particularly for non-communicable diseases such as cardiovascular disease and injury. Given Africa’s disproportionate burden of road traffic injuries, Stassen contributes his expertise in diverse research methodologies to enhance our understanding of road traffic injuries, and the effectiveness of post-collision care, aiming to reduce morbidity and mortality in these high-risk environments.
Emily Foote, Devon Air Ambulance, School of Emergency Medicine, Peninsula Deanery
 
Emily is a senior registrar in Emergency Medicine and a critical care doctor with the Devon Air Ambulance. Emily has been working with IMPACT on developing novel bystander led triage scores, assisting with the EXIT Project translation to practice work streams and most recently has developed an interest in the interaction between medical events at the wheel, injuries and outcomes. 

Dr Francois-Xavier Ageron

 

Dr Francois-Xavier Ageron is a Consultant in Emergency Medicine at the University Hospital of Lausanne, Switzerland. He first trained in emergency medicine in France and was involved in pre-hospital care and mountain search and rescue helicopter services in the Northern French Alps. He was Medical Director of the Northern French Alps Emergency Network and implemented the TRENAU Trauma System, leading research in trauma triage. After an MSc and PhD in Epidemiology at the London School of Hygiene and Tropical Medicine with the CRASH-2 and CRASH-3 teams, his research moved to bleeding and coagulation in the injured patient. He joined the Emergency Department and Trauma Centre of the Lausanne University Hospital (CHUV) to lead research projects in emergency medicine and trauma.

Dr Andrew J Murphy 

Andrew is a lecturer and head of the postgraduate division within the School of Medicine at the University of Dundee and an honorary clinical scientist with NHS Tayside. His specialist area is the biomechanics of human movement, and he has taught, conducted research, and held applied posts in this field in both the UK and China for over 15 years. His involvement with IMPACT is primarily in relation to providing biomechanical scrutiny of the safety and effectiveness of methods for extrication and handling casualties.
Ms Jessica Caterson
BMBCh BA (Oxon) MSc MRCS (Eng)

Jess is currently an Academic Clinical Fellow in General Surgery at Imperial College London and Imperial College Healthcare NHS Trust working at a London Major Trauma Centre. She completed a Masters in Health Data Science at LSHTM during which she began collaborating with IMPACT on data-driven projects. Her most recent work explored the impact of spinal cord injury in LMICs compared with HICs using the Lancet Global Burden of Disease dataset.  She has an interest in large-scale data collection and analysis, including applications for artificial intelligence, in improving post-collision care.

Dr Claire Baker
MPhys (Hons), MRes, PhD

Claire is a Research Fellow in Design Engineering at Imperial College London who leads interdisciplinary projects investigating how accessible sensor technology can be used to assist post-collision emergency response, with a focus on traumatic brain injury. She lectures in post-crash analysis as a leading expert in UK collision data. She contributes to UK and International Standards Organisation policy alongside delivering impactful projects such as the HIPER consumer cycle helmet rating programme.
